I Application filed June 20, 1908. Serial No. 822,66.

. My invention re ates to automatic blocking and coiling attachments for rolling mills.

As herein embodied, my invention is designed to provide means for causing sheet metal as it passes from the rolls, to assume a coil form either by winding u on a block or upon itself, depending upon t e thickness of the sheet.

An im ortant feature of my invention consists in tlie em loyment of a plurality of interchangeable hlocks, together with manually controlled means for automatically substituting one for another, the object being to avoid interruption andmake the operation practically continuous.

The accompanying drawings will serve to illustrate mechanism suitable for carrying my invention into effect.

Referring to the drawings: Figure 1, is a plan view showing the blocking and coiling attachments applied to a stri -mill. Fig. 2, is a view in front elevation t ereof. F1 3, is a plan'view of the block driving and s ifting mechanism. Fig. 4, is a vertical section showing the coiling attachment in use. Fig.

" Fig. 6. Fig. .8, is a detail cross section taken on the line .9, c of Fig. 6, and Figs. 9 and 10 are similar views. taken respectively on the lines a, s, and 8 8 of Fig. 6.

In the drawings, 1 and 2 r'e resent the rolls of a strip mill and 3, 3, the si e frames thereof, in which the rolls are mounted in the usual manner.

Ordinarily in the operation of the mill, sheet metal in stri form is fed between the rolls, and carried orward in suitable guides to a rotating block, such as is indicated at 4 upon which it is wound under more or less .tension and the block with the strip wound thereon is then removed, and another block placed in tinued.

Owing to the difliculty, uncertainty and danger incidental to hand blockin provislon is made herein for automaticafiy startingthestrip upon the block that is to say, g1v1n it the first few turns necessaryto cause the b ock to take hold and continue the windmg. For this pin ose, I em loy the mechanism illustrated in Figs. 4 an 5. The blocker shown consists of two-separable guide arms 5 and 6, which are mounted free to turn upon position and.the operation concross rods 7 and 8, and as arranged, form con-- tinuations of fixed strip guides 9 and 10, the parts 5 and 9 constitutmg the upper sectional guide and the parts 6 and 10, constitutin the lower sectional guide. The guides 9 an 10 are arran ed one in contact with each roll and are have ed or tapered to serve as strippers. At their free ends, the guide arms 5 and 6, are curved and combine as shown in Fig. 5, to loosely encircle the block, being connected and held thus by a latch 11 operated by a lever 12. A late 13, pivoted upon the lower guide arm 6, as a curved ed e conformin ap roximately to the circum erence of the 100 and a straight edge tangential thereto. Co-actin with the plate, there is a spring ressed tel escoping rod 14, which forces t e same toward the block. The arrangement is such that as a strip comes from the rolls, it passes through the guides, then outward .between the arms 5 and 6 to the,

block and around the same until it meets the curved edge of the plate 13, which resses the end of the strip in close contact with the block until it is caught under the horizontal moving portion of the strip. As the block' is usually driven through a friction clutch, hereinafter referred to, at a slightly greater speed than the rolls, the strip is at' once drawn taut and wound thereon under more or less tension. In order to avoid unnecessary friction, each of the guide arms 5 and 6 is provided with one or more rollers 15, which are preferably secured to the curved ends thereof and coact with the block, but may also be employed throughout the straight portions if desired. After the strip has been properly started upon the block, the latch 11 is. released by pressure upon the lever 12, and the arms 5 and 6 are swung require( set to cause it to wind upon.

itself or assume a coil form. A device suitable for this purpose is shown in Figs. 1, 2' and 4, mounted upon a frame 19, which is.

hinged at to one of the side frames 3, and as arranged, may be swung around across the front of the mill, as shown in Figs. 1 and 4 to receive the strip as it comes from the rolls. The coiler, as shown in- Fig. 4, consists'essentially of three cooperating rolls 21, 22, 23, which are provided with terminal intermeshing gears 24, 25, 26, driven through gears 27, 28, from the block spindle. The rolls 21 and 22 arranged side by side, at a suitable dis tance apart, are mounted in fixed bearings in the frame 19. The roll 23, extending parallel with the rolls 21 and 22, is mounted 1n 7 frame 19. I

A Well known form of screw adjustment is employed for moving the roll 23 relative to the rolls 21 and 22 and is operated by means of a hand wheel 3] through suitable gearing, such as the worm and bevel gearing indicated at 32, 33. When the guide arms 5, 6, are swung clear of the block and the coiler is in use, as shown in Fi 4, temporary guides 34, are employed, leadm from the fixed guides 9 and 1 0" to the rols of the coiler. Such guides may be in the form of strips, plates, or the like, and are bolted or otherwise secured in pos tion as shown.

Heretofore the time occupied in removing a blockupon'which the strip is Wound and in placing another block in osition has greatly reduced the effective per1od of operation of the mill as the latter runs idly while the exchange is being made, and the resulting loss constitutes an item of considerable expense to the operating company. In order to avoid 'such interruptions and make the operation practically continuous, I employ ings 36-andfixed upon the projecting end of the shaft, there is a cross-arm 37 )rovided with terminal bearin s 38, in whlch twin block supporting spind es 39, 39 are mounted free to turn. The spindles 39 39 are square throughout the greater portion of their length, as indicated at 40, and the blocks 4,

4,.etc.,are bored out and similarly shaped to clutch of the positive type. Figs. 3 and 6, each spindle is provided with a fit the spindles. The blocks are thus secured in driving relation and caused to rotate with the spindles, and being free to slide thereon, may be slipped on or off the spindles at-will.

Extending parallel with the shaft 35 and alined with the inner block s indle 39, there is a shaft 42, which is mounte in bearings 43, and is driven eitherdirectly by a belt pulley 44, through a friction clutch 46, as shown in Fig. 3, or indirectly through such a clutch and the gears 47, 48, as in Figs. 1 and 2.

When the direct drive is employed, the ulley and clutch are mounted upon the 's aft 42, the pulley being loose and the sliding member of the clutch splined thereon.

Then the drive is indirect, the pulley and so clutch are carried by the shaft 35, the pulley being loose thereon and the sliding member of the clutch and the gear 47, mounted upon a sleeve 49, which is free to turn upon the shaft. upon the sleeve and is shifted by means of a lever 50, connected therewith through -a forked arm 51, in the usual manner.

From the foregoing it will be seen that when the clutch is thrown in, the shaft 42 is connected in driving relation with the pulley 44, and that as the clutch is thrown out, there is no further transmission of power, and the shaft ceases to rotate. a

.The block spindles 39 and 39 are driven direct by the shaft 42, through a second As shown in terminal clutch member 53, with which a sliding clutch sleeve 54, splined upon the shaft-42, is designed to co-act as a spindle is brought into alinement therewith. This clutch sleeve 54 also controls the transmission of power from the shaft 42 to the shaft 35, through the gears 55, 56, and-friction clutch 57. The arrangement is such that as the clutch sleeve is shifted in one direction, it interlocks with the terminal clutch mem-' ber of the alined block spindle and connects the same in driving relation with the shaft 42, and when shifted in the opposite direction, it interlocks with the gear 55 andthrough this gear and the gear56, the shaft 35 is rotated ,as re juired to Withdraw the block upon which tie metal is wound and move the other into operative position relative to the shaft 42 and the guides through which the metal passes as it comes from the rolls.

The shaft 35 is normally locked against bolt and pin co-act with oppositely ,dis-

posed lugs or projections 61 on the terminal cross arm 37 of the shaft.

A groove 62 is formed transverselyof the The sliding clutch member is splined 85 I guides 60, and through this groovethe lugs 61 passes the shaft 35 is rotated. The end of the spring-seated pin 59 projects into the groove and is rounded to yield in the direction of its length as'the lug strikes it, permitting the lug to pass and being thereafter returned to position bythe action of its spring. At a point below 'the pin, the

bolt 58 extends' across the groove and serves as a positive stop to limit the movement of the-lug, which in being thus caught between the pin and bolt holdsthe shaft 35- against further rotation until the bolt is withdrawn. l

The release of the shaft'35 by the withdrawal of the bolt and the throwing in of the clutch 54 for the transmission of ower from shaft 42 to shaft 35, is controlle by a foot lever 63, fast u on a shaft 64. Mount-" ed upon this shaft, t ere are two crank'arms 65 and 66, one of which is connected through link 67, with a lever 68, pivoted at 69, and

' stud of a the other is similarly connected by a link 70, with a lever 71 pivoted at 72.

The lever 68, is slotted at its free end and projecting through the slot there is a pin or look 73, which is movable in guides 74, and is bore out or shaped to serveas a bearing for the free end of each block spindle when in operative position. The

bearing block, as mounted, is alined with I shaft 42. It is advanced toward the spindle I which co-act with a by means of a spring 75, acting through the lever 68, and is iven motion in the op osite direction and shifted clear of the spin le by the foot lever-63 through the connection described.

The lever 71 is forked at its u per end to 006 crate with the sliding clutc sleeve 54, an is connected through a link 76 and lever 77, pivoted at 78, with a cam 79, fast upon the shaft 35, which is designed to assist the spring 75, acting through the levers, links, etc. described, to throw the clutch 54 out of engagement with the gear 55.

The cam is provided at diametrically opposite points with shaped portions 80, pin or stud 81 of the lever 77;. As the clutch sleeve 54 is thrown in with the gear 55, the period of engagement is limited by the operation of the cam acting through the lever 77, link 76 and lever 71, to the time re uired for the shaft 35 to rotate through haf or such portion of a revolution as is necessary to move one block ont and another block lnto position.

'to release the terminal lug of the cross-arm 37. For. this purpose a connection is provided between'the bolt 58 and the lever 71,

55 in the form of a latch 82, which is pivoted to the bolt at 83 and is provided with a hooked end 84, which normall takes over an off-set pin or stud 85 of t e lever, 71. As arranged, the first part of the movement of the lever 71 to throw in' the clutch, serves to carry the bolt 58 clear of the groove 62, leaving the lug of the cross-arm 37 free to pass out asthe shaft begins to rotate,

The release of the bolt is effected automatically b meansof a second cam 86, fast upon the s aft 35, which 006 erates with a trip-arm 87, pivoted at 88. T e cam 86 acts after the lug 61 has passed'out of the groove 62, to rock the trip-arm 87, and the latter enbetween the pin and bolt, as above described.

As the operation will be generally understood from the foregoing, I will describe the same briefly: When the metal rolled is of a thickness such as to admit of being blocked, the frame carrying the coiler is swung around to one side, as indicated b dotted lines in Fig. 2, and after a block has een placed upon one of the spindles; such as 39 for example, and moved into position, as-shown in Fig. 5, the guide arms 5 and 6 are closed about the same and locked by the latch 11. The mill is then started up and the lever 50 is shifted to throw in the gearing by which the block s indle is driven. As the strip comes from the rolls, it is carried by the guides to the rotating block upon which it winds "under more or less tension, as above described, and after it has been fairly started upon the block, the latch 11 is disengaged and the guides are swung clear as shown in Fig. 4. Thereafter the winding continues ,until the entire strip is blocked. I

During the operation just described, an other block is placed upon the .adjoining spindle 39, and in order now to move the same into position and remove the block on which the stri is wound, the foot lever 63 is depressed an through the connection described, shifts the bearing block 73 and clutch 54 clear of the block spindle 39 and throws the clutch in with the gear 55, for the transmission of power to the shaft 35. The automatic release of the locking mechanism follows and the shaft 35 is given a half turn as required to substitute one block for the other, and is then looked against further rotation until the foot lever is again depressed. Through the action of the spring 75, the hearing block 73 is advanced toward the block spindle 39", the free end of which enters the socket or opening therein and the cam 80 acts to shift the clutch 54 to connect the-spindle 39 in driving relation with the shaft 42. After the guides 5 and 6 have been moved into position and secured about the block, the operation is repeated.

l/Vhen the rolled strip exceeds a certain thickness, it is preferably run through the coiler, which is swung around into position, as shown in Figs. 1 and 4, and is operatively connected with the mill by means of the guides 34. The strip as it comes from the rolls is directed by the guides to the coiler and in passing through the same is given the required set, causing it to wind upon itself and assume coil form, as indicated by the dotted lines in Fig. l.
